Recently after farming 15 paragon levels I decided I wanted to up my MP farming to start getting better drops. I have about 60 mil right now and I want to up my damage and I also need to pick up some life steal.

I was considering picking up a skorn with life steal but the market is pretty bad for 1300ish dps/175+% crit damage.

I would love to move to a thing of the deep for the pickup range so that I can better use some ranged skills like Grave Injustice. I love my build but I definitely need life steal.

Honestly, I think you'd be best served focusing on paragon farming. The drops will come as you gain more paragon. Higher MP doesn't give you higher quality drops, and your killing efficiency takes a big hit the higher you go. IMHO, if you want to do item farming, stick with MP0 or 1, stack a bit of MF and continue grinding paragon.

That said, if you're really set on doing high MP for the lulz, you'll definitely want more EHP. Your AR looks OK, but HP is pretty low. Maybe consider getting some Blackthorne's pants with 200+ vit and 100+ int. Should up your HP quite a bit and give you some extra LoH. You might look for a new Zuni Marrow too, with 150+ vit.

I cruise through MP0 & MP1 as fast as can be. My build is intended to max MP and gold find (secret weapon for breaking stuff: Spirit Barrage - Maintou - this is awesome for breaking pots, doors and barricades so you're not wasting mana or time!)... second secret is the use of Locust Swarm - Pestilence. It has been shared by some high lievel players recently and in high-density areas you literally can follow the trail of your Locust Swarm and watch the whites drop like flies.

Life Steal isn't nearly as important on MP0 or 1 as you can easily survive using a Thing of The Deep (Health Globes) plus Leeching Beasts. I survive very well against Reflect Packs by just taking an extra second and spacing my attacks out.
